METHOD AND APPARATUS FOR TREATING HAIR Application fled Kay 80, 1982. Serial No. 612,419.

This invention relates to a new and imroved method, com sition and apparatus or treating hair for lmparting a permanent wave thereto. i 5 It is the principal ob ect of my nvention to provide a permanent wave withln the shortest possible time without developing excessive heat harmful to the ban and uncomfortable to the person, without the use of electricity or special apparatus.

Another object of my invention is the rovision of a novel and improved compoun developing readily the heat required while the hair is protected against'undue drying and from becoming brittle in order-to maintain it in a healthy condition.

A further object of my invention is the rovision of a novel and inexpensive, yet efiicient method of treating the hair for 1mparting a permanent wave thereto Without the slightest inconvenience to the person treated, and one which will last for a considerable time. 7

A still further object of my invention is the provision of suitable the heat developin ingredients and a protecting cover there or.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds, and W111 then be more specifically efined in the appended claims.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 illustrates the construction of the inner core of my novel and improved apparatus for, treating hair according to my method for imparting a permanent wave thereto- I Fig. 2 is a perspective view of the outer member or roll used in the production of a permanent wave, according to my method, spread out. r

Fig. 3 is an end view of said outer member.

mem er. Fig. 5 is a sectional end view of the entire roll with outer and inner member.

In the practical embodiment of my inven-' tion, strands of the hair to be treated are pads containing Fi 4 is a detail view of a roll or outer first wound about a stick or rod 10, as indicated at 11, and tied to the rod by means of a string or cord 12. About the hair is then wound a strip of textile fabric, such as for instance cotton flannel interlining 13 soaked in an ammonia lotion for protecting and softening the hair.

The interlining 13 is then covered by a strip of tin foil 14 and formed into a roll, constituting an inner member.

The outer member into which the nner member is placed, contains the heating bod comprising a tin foil pocket 15, in whic a flannel bag 16 contains a com ound, preferv v ably in powder form compose of a mixture 65' of calcium oxide or live lime and calcium hydrate or slaked lime in certain proportions, as will hereinafter be more fully explained.

The tin foil pocket 15 is provided with a plurality of openings 17 allowing the penetration of water into the pocket, which is .covered by an outer cover 18 vpreferabl of tin foil and also having numerous per orations 19. The entire'body is then rolled up into a paper cover, preferably wax aper 20. In the practical execution of my met 0d I use for the construction of the heating element preferably 55% of live lime, 30% of calciumhydrate, 10% calcium oxide and 5% of a water and ammonia lotion.

In use, the hair is first wound about the rod 10 as shown in Figure 1, and then secured thereto by means of the band 12 the end near to the scalp of. this band is .clamped into a slot 21 of the rodwhile the opposite end is knotted about the rod. A protecting shield having first been placed on the hair strand near the scalp and is held in position by any suitable customary clamping means. The interlining 13 is then soaked with an ammonia water solution or lotion tending to protect and soften the-hair, and the cover of tin foil 14 is then wound about the rod and hair and held thereon in any suitable manner.

Then the roll 20 is prepared for endwise fitting over the hair, b soaking the pad cover 18 and pocket 15 wit water or other suitable fluid to develop heat within the pocket by the slaking of the lime while the calcium hydrate will prevent the development of an excess of mo heat. The pad 15 and cover 18 are then rolled into the roll 20 of wax paper and placed over the hair wound about the rod. The roll is left about 15 minutes on the hair and upon its removal it will be found that a permanent wave has been formed in the hair.

It will be understood that Ihave disclosed the preferred form of my device only as one example of the many possible ways to practically-construct the same and that I may make such changes in the general arrangement and the construct-ion of theminor details, as well as in the ingredients used and in their proportions of mixture as come within the scope of the appended claims without departure from the spirit of my invention and the principles involved.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a device of the character described a heat developing body comprising a fabric bag containing calcium oxide and calcium hydrate, a perforated tin foil cover therefor in a perforated tin foil wrapper, arid a wax paper outer cover for the Whole.

2. A compound for creating heat in hair waving apparatus consisting of 55% of live lime, 30% of calcium hydrate, 10% of calcium oxide and 5% of a Water and ammonia lotion.

3. In the making of a permanent hair wave, the process which consists in soaking a pro.- tecting cover for the hair with a water-ammonia lotion, and winding about the same a heating roll containing calcium hydrate and calcium oxide in a Water ammonia lotion, and

subjecting the hair to 15 minutes treatment.
